ECU repair

When an ECU is defective you are directed in most cases to buy a brand new one. Before you buy a new one it is a recommendation to contact us! Karreman Engineering is able to retrieve the content of your old/damaged ECU and copy it to a 2^nd hand one. You can save a large amount of money compared to buying a new one.

Also if your ECU is damaged it is a recommendation to contact us. Karreman Engineering is able to repair most ECUs with a glance of the costs from a brand new one. If we aren’t able to do the job our partners can.

Common errors are broken or damaged end-stages for both injectors and ignition coils (were applicable) which can be easily replaced.

Besides ECU repair we can also repair pixel damage on your instrument cluster. Please have a look at this link below for an overview of currently supported instrument cluster repairs.
